Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed March 10, 1913. Serial No. 753,243.

T0 all whom t may concern.'

Be it known that I, FRED WV. AXTELL, a citizen of the United States, residing at Fort lVorth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Valves, of which the following is a specification.

My invention relates to valves and particularly to valves for tanks, and the object is to provide a simple valve which is easily operated and is provided with an air line down through the valve and into which a pipe can be screwed and extended to the top of the tank so that the small wire which is used ordinarily for raising tank valves can be dispensed with and the trouble which this wire causes avoided. The advantage of such construction is its simplicity and the air line coming down through the valve to the underside will allow the pipes to be drained quickly.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is a side elevation of the valve and its cup. Fig. 2 is a vertical section of the same. Fig. 3 is a side elevation of the valve. Fig. 4 is a horizontal section on the line A-B shown in Fig. 2. Fig. 5 is a horizontal section, taken on the line C-D of Fig. 2.

Similar characters of reference are used to indicate the same parts throughout the several views.

A valve cup 1 may be screwed on a pipe 2 which projects up through the bottom of a tank. An open top cap 3 is screwed on the cup 1 and this cap has a ground beveled seat 5 for the valve 4. The valve 4 is carried by a spider-like structure 6 which has stop lugs 7 which rest on an annular stop shoulder 8 in the cup 1. The carrying member 6 has a stem 9 and a guide member 10 projects from the inner wall of cup 1 and is perforated for the stem 9 to move freely therethrough. This forms a guide for the vertical movement and centering of the carrying member 6. This carrying member has a cavity 11 in the upper side to receive the lower part of the valve 4. Between the stem 9 and the seat 11 for the valve 4, the

carrying` member has a tapering portionlv and the carrying member has a central opening to a point near the stem 9 and a plurality of perforations 12 lead from the interior of the carrying member to the outside thereof to provide air passages for draining purposes. A stud pipe 13 is screwed into the carrying member 6 and forms an air passage through the carrying member and communicates with the air passages 12. Any suitable pipe 14 may be screwed into the stub pipe 13 to be extended to the top of the tank.

When the valve is in operation the carrying member is resting on the annular stop shoulder 8 by reason of the stop lugs 7 and water passes up through the pipe 2 and between the carrying member and the valve and out through the discharge spout or nozzle 15. When the water is to be cut off, the valve 4 is drawn against its seat 5 by means of the operating pipe 14. When the water is cut off air will be let down through the pipe 14 and the carrying member 6 for draining the pipes below. The valve 4 is held in place in its seat by an annular stop shoulder 16 on the stub pipe 13. l/Vhen the valve is to be opened, its own weight and the weight of the pipe 14 will be sufficient to open the same when the pipe 14 is released. A seal is effected between the cup 1 and the cap 3 by means of a gasket 17 when the cap is screwed down.

wWhat I claim, is,

1. A valve comprising a perforated block of yielding material and a carrying member therefor, said carrying member having an air passage therethrough, an open top cup having a pipe connection at the lower end and a beveled seat at the upper end for said block and an annular interior stop shoulder, and lugs rigid with said carrying member spacing the carrying member from the cup and forming a support for the carrying member resting on said stop shoulder.

2. A valve comprising an open top cup provided with a pipe connection at one end and a beveled seat within the other end, a perforated valve member having a rounded surface adapted to engage said seat, a carrying member having a cavity for said valve member and an operating stem engaging said carrying member and closing the perforation in said valve, said stem and carrying member having air passages therethrough, and means for supporting, saidv carrying member Within said Cup when the valve is open.

3. A valve comprising an open top cupi, provided with a pipe connection at one end anda beveled Seat Within the other. end and an annular interior stop shoulder intermediate the ends thereof and a perforated guiding member, a perforated valve member havingy a. rounded surface-to engagesad seat, a Carrying member havingy a` Cavi-.ty for saldi valve member and: an` operating Stem engaging said carrying member and' having an annular stop for holding the; valve member in said cavity and Closing Jche` perforation in the valve member, said Carr mg member and. Said stem having air passages therethrough, sald earrymg member having lugs to engage said stop shoulder7 and guiding stem engaging said earrymg 20 FRED' W. AXTELL.
